Lay on Hands is a Holy-based spell that instantly fills your target with life. Considered an "emergency" ability, in that due to its long cooldown it should only be used when it's really needed.

Talent improvement

Improved Lay on Hands - (2 Ranks) Reduces cooldown by 2/4 minutes, adds 25/50% armor buff.

Notes

Tankadins can consider this as a long cooldown "oh s**t button". Turn on the auto-self cast option or create a macro. When your health is dangerously low, use it immediately to heal yourself back to full health.
This ability is completely independent of the amount of Healing the caster has. It always heals the target for the amount of health the caster has.

Patch changes

Patch 3.0.2 (2008-10-14): Does not drain all of the player's mana anymore. Cooldown reduced to 20 minutes.
